CHARLES VAN MIDDLESWORTH, OF BROOKLYN, NEW YORK, ASSIGNOR TO THE VAN DYCK GRAVURE COMPANY, OF NEW YORK,

FEEDING MECHANISM FOR PAPER;

Patented Nov. '7, 1911.

Original application filed November 23, 1908. Serial No. 464,096. Divided and this application filed October 15, 1969, Serial No. 522,753.

To all whom it may concern;

Be it known that I, CHARLES VAN Mn)- nLnswoRTH, of the borough of Brooklyn, in the county of Kings, and in the State of New York. have invented a certain new and useful Improvement in Feeding Mechanism for Paper, and do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to an improvement in, paper feeding mechanisms for printing presses, and relates especially to an improvement whereby paper can be more accurately fed to a press, so that in case multiple impressions are to be made upon the same sheet of paper a perfect alinemcnt of the different impressions can be obtained.

This is a divisional application of my application for printing machines, Serial No. 464,096, filed November 23rd, 1908.

I have shown one embodiment of my invention in the accompanying drawings, in whi'ch- Figure 1 is a side elevation of a printing press equipped with my improvement; Fig. 2 is a fraglnental plan view of the same; and Fig. 3 is an enlarged view of a detail.

In the accompanying drawings, 1 represents a side standard for supporting the parts of the printing machine, only one of these standards being shown in Fig. 1, although there is a similar standard on the other side of the machine. Supported in the standards 1 there is an impression cylinder 3 having its journals 4 located in an eccentric sleeve 5 supported in thejournal bearings 6. The eccentric sleeve 5 has attached thereto an arm 7, to the end of which is attached a link 8 designed to connect the eccentric sleeve with a manually-operated lever 9. The link 8 andthe lower portion of the manuall \'-opcratcd lever 9 constitute a toggle nu-chanism. The lower end of the lever 9 is pivoted at 10 to the side standard 1, while the other end of the lever provided with a handle 11, so that the same may be conveniently moved to raise and lower the impression cylinder.

A feeding table 12 is adapted to be supported at its outer end from the standards, and at its inner end from the journals This is accomplished in the following manncr:-'lhc table has attached thereto on its under face a rigid frame or supporting bracket 13, the table being pivoted ,to the same at 14 near the outer end of the table, while the inner end of the table is supported by means of an adjustable screw 15, screwthreaded in an upright 16 of the bracket 13, and having its headlocated in contact with so the under face of the table. The outer end of the bracket 13 is supported from the standards 1 and 2 through the agency of links 16*, one of whichis situated on either side of the printing machine. The links 16* are connected at their lower. ends to the standards by means of an integral bracket 17 projecting from each of the side standards. The inner end of the supporting bracket 13 is supported directly upon the eccentric sleeve 5. at each end of the impression cylinder, as shown in Fig; 3, the bracket for this purpose being provided with a circular housing 18 surrounding the eccentric sleeve 5. It will thus be seen that by the parts above described, a movement of the handle '11 effects a movement simultaneouslyeither up or down of the impression cylinder 3 and the feeding table '12. .The supporting bracket 13 also supports journal bearings 19, located on either side of the impression cylinder, for a shaft 20, which carries a series of drop guides 21. The bearings 19 are situated in detachable arms 22, which are bolted to the upper face of the circular housing 18 by means of the bolts 23.

I prevent the shaft 20 from becoming displaced out of its proper position in a lateral direction, by inserting screws 24- in. the jour nal bearings 19 so as to register with depressions or grooves located at these points in the shaft 20.

Each of the drop guides 21 comprises a bracket 25 having a split sleeve adapted to surround the shaft- 20 and be tightened upon the same by means of a screw 26 having a thumb-piece 27. In the end of the bracket 25 I support, by means of a journal bearing 28, a rod 29, the inner end of which is screwthreaded so as to carry a milled nut 30, which nut 30 is situated in an opening 31 on the end of the bracket 25. A spring 32 is provided around the rod 29, between the journal bearing 28 and the milled nut 30, so as to press the milled nut 30 continually in a rearward direction against the bracket The nut 30 is furthermore provided with an annular recess 33 in which a screwthreaded pin is adapted to be projected and tightened so as to maintain the milled nut in its adjusted position. The end of the rod carries a depending arm 35, which is located in a vertical position. To this arm is riveted a curved guide 36. the detail construction of which forms no part of the im ention intended to he covered by this application. In the downward position of the drop guide, the arm is designed t.o rest against a tongue. 38 which extends from beneath the table 12, from which it is supported by means of a transverse strip 39, as shown in Fig. 2.

The shaft 20 carries a series of drop guides of the character described and the table 12 carries a series of tongues 38 coiiperating with said drop guides. It will now be ob served that a movement of the handle 11 so {lb to raise or lower the lll'APl'CSSlOll cylinder 2-). results simultaneously in a corresponding movement of the drop guides 21 and the table Iiinith its at ached tongues While I have described my invention abo e in detail, l \S'iSll it to be understood that many changes might be made therein without (hpuit lug from the spirit thereof.

it claim:

' l. in a device of the character described, the combination of a feeding table, a printing eouplefa rigid frame upon which the feeding table and one member of the couple are both mounted, and means for adiusting the frame and table to and from the other member of the printing couple.

2. In a device of the character described, the con'ibination of a feeding table, a printing couple, guides for controlling the feed in of paper from the table, a frame upon which the table, one member of the printing couple and the guides are all carried, and means for adjusting the frame to and from the other member of the printing couple.

3. In a device of the. character described, the combination of a feeding table, a printing couple, a. rigid frame upon which the feeding table and one member of the couple are both mounted, and a toggle mechanism for adjusting the frame and table to and from the other member of the printing couple.

t. In a device of the character described, the combination of a feeding table. a printing; couple, guides for controlling; the feed ing of paper from the table, a frame upon which the table, one member of the printing couple and the guides are all carried, and a toggle. mechanism for adjusting the frame to and from the other member of the printing couple.

In testimony that I claim the foregoing ll hare hereunto set my hand.
